The channels that an antenna receives depend on the strength of the antenna itself and the area where it is located. To see what channels are available, locally, check the FCC's DTV Reception Maps and enter the location where the antenna is used.
Different types of antenna are available depending on the signal strength of the channel, so it is necessary to see which channels are needed and what type of antenna can access those channels. In most cases, the channels that come through are usually local channels in both standard definition and high definition. There are also additional channels for movies and music videos.
The most popular antennas to buy are antennas, which have a 35-mile range. As of 2015, they can be bought for as little as $24.99 on Amazon.com. For a stronger signal, 50-mile to 60-mile antennas are available for a higher price, and these offer a wider variety of channel options.
Setting up these TV antennas is very easy, and it is usually just a matter of connecting the antenna to the television and putting the antenna in a good location. An outdoor antenna can be mounted on a roof or on the side of a home. Indoor antennas can also be mounted on a wall, or placed near the television set.
